In contemporary analytic philosophy, a fictionalist view of one type or another has been proposed in areas like philosophy of language, metaethics, and metaontology, and extended over areas like philosophy of mathematics, philosophy of mind, and even philosophy of science. Critical responses, in every such area, have also been offered by defenders of realism, eliminativist anti-realism, non-cognitivism, Meinongianism, deflationism, etc. Nevertheless, there has been little interaction between proponents and critics of fictionalism across these areas. This workshop attempts to increase such interaction and see what (if anything) can be learned from its possible outcomes.
